Answer Details
High temperature and pressure convert sandstone to quartzite. Sandstone is a sedimentary rock composed of sand-sized mineral particles or rock fragments. When sandstone undergoes high temperature and pressure, the individual grains of sand are fused together, forming a harder and more compact rock called quartzite. This process, known as metamorphism, causes the sand grains to recrystallize and fuse together, creating a dense and durable rock that is resistant to erosion and weathering. Quartzite is mainly composed of quartz, with minor amounts of other minerals such as feldspar, mica, and iron oxide. It is commonly used as a construction material due to its strength and durability.
